Signed elementary product

WebSigned Elementary Product An n n matrix A has n! elementary products. There are the products of the form a 1j 1 a 2j 2 ··· a nj n, where (j 1, j 2, …, j n) is a permutation of the set {1, 2, …, n}. By a signed elementary product from A we shall mean an elementary a a ··· a multiplied by +1 or -1. We use +

All anti-diagonal matrices are also persymmetric. The product of two anti-diagonal matrices is a diagonal matrix. Furthermore, the product of an anti-diagonal matrix with a diagonal matrix is anti-diagonal, as is the product of a diagonal matrix with an anti-diagonal matrix. An anti-diagonal matrix is invertible if and only if the entries on the diagonal from the lower left co… WebHowever, a 4 by 4 matrix requires the computation of 4+4! = 28 signed elementary products.
